General Description

These are the last MIDI observations of the Nova V1280 Sco.

The N band magnitude of the source has brightened to reach about 6O Jy, and the
 flux should be close to its maximum. The correlated flux has decreased with the
 increase of the angular diameter of the source but it is not a limiting factor.
 The observations should be performed within the 3 weeks from now, when the N band
 flux is still high.

The source is now as extended as 15mas and can be resolved by any baseline from
 32 to 90m, but in order to keep the consistancy with the previous observations a
 baseline between 40 and 70m is preferred. There is no need of a specific PA angle
 but the largest PA coverage would provide the best constraints on the source putative
 asymetry.

All the technical coordinators of this DDT proposal are warmly thanked for the success
 of these observations.
